In this paper, we employ the beam from the multimode laser diode (LD) for irradiation, which includes the intensity modulation due to the opticcal beat, and the electromagnetic radiation  from a gunn oscillator (50.3 GHz) to be incident on the photoconductive antenna.   Using an electric spectrum analyzer and a Lock-in amplifier we detect the ac signal which can be assigned to the ac current of the frequency |f1-f2| and the dc signal which may be assigned to the thermoelectromotive effect or the rectification effect in the photoconductive antena.   The status of the intensity fluctuation in the LD beam is investigated using a transmitter-receiver system of the sub-THz radiation with two photoconductive antenas.   It was shown that there appear drastic changes depending on the power of feed back beam to the LD.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15053/0000000295","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"海上保安大学校"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15053/2006.21.03","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088865","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-2951","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森川, 治"},{"creatorName":"モリカワ, オサム","creatorNameLang":"ja-Kana"},{"creatorName":"MORIKAWA, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"265","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"谷, 正彦"},{"creatorName":"タニ, マサヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"613","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤田, 正実"},{"creatorName":"フジタ, マサミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"614","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"萩行, 正憲"},{"creatorName":"ハンギョウ, マサノリ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"615","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TANI, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"616","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"FUJITA, Masami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"617","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HANGYO, Masanori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"618","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-06-18"}],"displaytype":"detail","filename":"2_50-1-72-03_Morikawa.pdf","filesize":[{"value":"759.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"マルチモード半導体レーザの高速光強度揺らぎを利用したサブテラヘルツ帯のヘテロダイン受信器","url":"https://jcga.repo.nii.ac.jp/record/295/files/2_50-1-72-03_Morikawa.pdf"},"version_id":"66a29de1-c205-4b86-8c05-d2143dc77451"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"マルチモード半導体レーザの高速光強度揺らぎを利用したサブテラヘルツ帯のヘテロダイン受信器","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マルチモード半導体レーザの高速光強度揺らぎを利用したサブテラヘルツ帯のヘテロダイン受信器","subitem_title_language":"ja"},{"subitem_title":"A Heterodyne Receiver in the sib-THz Region Utlizing Rapid Intensity Fluctuation in a Beam from a Multimode Laser Diode","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["69"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-06-18"},"publish_date":"2023-06-18","publish_status":"0","recid":"295","relation_version_is_last":true,"title":["マルチモード半導体レーザの高速光強度揺らぎを利用したサブテラヘルツ帯のヘテロダイン受信器"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-10-10T00:21:38.556640+00:00"}
